If they where edited, those are just taking out illegal camping spots that people would whore all day long. Basically putting a wall to block off a area or something of that nature, but just using simple terms on that. Shouldn't affect textures to that degree though, with any map making/changes.

I saw that also latino. Let me add that it only seems to happen after you've been in spectate and flying around certain parts of the map (when it goes black etc) that show those lines. Afterward those lines show up as in your pic.
